Internal blowing cleaning blade type threshing roller

Abstract

The invention discloses an internal blowing cleaning blade type threshing roller, which comprises a roller body. A threshing knife lug for mounting a threshing knife is arranged on the outer peripheral surface of the roller body. The threshing roller further comprises a threshing roller shaft; the two ends of the threshing roller shaft are mounted through bearing bases; the roller body is internally hollow; the roller body sleeves the middle part of the threshing roller shaft and can rotate along with the threshing roller shaft; a distribution cavity is reserved between the outer circumferential face of the threshing roller shaft and the inner wall of the roller body; a main pipeline and branch pipelines are arranged in the threshing roller shaft; the main pipeline is arranged in the axialdirection of the threshing roller shaft; one end of the main pipeline is communicated with a rotary connector; the distribution cavity is communicated with the main pipeline through the branch pipelines; cleaning holes are formed in the circumferential face of the roller body; the cleaning holes are internally communicated with the distribution cavity; and spray heads are arranged on cleaning hole outlets. The nozzle is arranged in the threshing roller, gas or other fluid cleaning media enter the threshing roller with the hollow interior through the rotary connector and are sprayed out of thenozzle to clean the threshing knife lug and the threshing knife, so that sharpness and cleanliness of the threshing knife are kept all the time, labor consumption and the equipment failure rate are greatly reduced, and production efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tobacco beating machinery, in particular to an internal blowing and cleaning blade type beating roller. Background technique [0002] In the tobacco processing link, the separation of the stems of the tobacco leaves is one of the important links for the tobacco leaves to finally become cigarette products. However, during the leaf threshing process, due to the extrusion and friction between the blade and the tobacco leaves, often Adhering to a layer of tobacco material affects the tearing effect of the blade ear seat. If it is left untreated for a long time, this layer of tobacco material will also corrode the blade ear seat, reduce the life of the blade, and affect the failure rate of the equipment. Currently Most of them adopt the method of opening the leaf thresher to clean up the tobacco attachment after stopping production to keep the blade sharp and clean. Cleaning is time-consuming and laborious, wa...

[0002] In the tobacco processing link, the separation of the stems of the tobacco leaves is one of the important links for the tobacco leaves to finally become cigarette products. However, during the leaf threshing process, due to the extrusion and friction between the blade and the tobacco leaves, often Adhering to a layer of tobacco material affects the tearing effect of the blade ear seat. If it is left untreated for a long time, this layer of tobacco material will also corrode the blade ear seat, reduce the life of the blade, and affect the failure rate of the equipment. Currently Most of them use the method of opening the leaf thresher to clean the layer of tobacco attachment after the shutdown to keep the blade sharp and clean. Cleaning is time-consuming and laborious, wasting production time and consuming a lot of labor.
